rlhis invention relates tov an automatic self sealing trap land has forits prime object to provide means for auton'iatically'fillf ing thesealing trap associated with the usual waste pipeleading from alixturesuch asa wash basin or the like should the same become empty.

A furtherV object of the invent-ion is to provide an apparatus offithis'nature which may be readily installed as 4is .the ordinary trap 'and onewhich will be. reliable in op-f eration, simple in construction,eiiicient and l well Vadapted to the purpose for which it is designed.'j Y n lVVithythe above and numerousjother objects in view as willappearas the vdescrip-l tionprogresses, the invention residesin vcerf l tainnovel features of-construction, and inf the combination and arrangementlof' parts aswill be'hereinafter more fully described and claimed. y YIn the drawing: Y A V Y Figure 1V is an elevation oftheapparatusembodying the( features of my,` inventionV showing the same as applied.Y y

Figure 2 is an elevation thereof showing the casingvremoved, and

Figure 3 is a vertical section tliroughthefl casing and the portion ofthe trap passing therethrough. Referring to thel drawing in detail itvwill be seen that 1 designates an ordinaiyfwaste Vpipepassing throughthe usual wally flange- 2., A fixture such as an' ordinary wash `basinis shownA at 3 having the tail piece sealing trap indicated generally atA is `disposed between the Viixturejtail'piece 4" and the end of thewaste pipe l being held in place by lock nuts 5 `and 6. rlhe trapproperindicated at P'is substantially shaped including the short armvfthe'end of which is connected to Vloclli'iut and therlong arm l?) theend ofwhich is`con- ,nected to lock nut 5. An opening 9l is pro-fV videdin the longer-leg8 a distance below its 'upper ends.. A vcasing lO'isdisposed 1 y aboutV the longer'leg V8 and ,encloses the opening 9, saidopening being situatedad* jacent the upper endfof` this casing. rAn

inverted U-shaped pipe 12is connected to a vthe longer leg 8 as at 13adjacent the bottom '-of ,the casing 10 and the other end thereofterminates within the casi-ng. 'I hispipe .12 V'acts as a'siphon as willbe explained hereinhoused within the casing and havingfthe after.capacity of the 10 should `i he' greater than thatof the trap. It iscustomary that the trap P lioldabout onequa'r-.- g j ter lof a rpintofwater `aiidfthe casing, there-` j fore, should be"constructed ytoholdabout onehalf of a pint of water@ As ywater 'iiows-l from'l nthethroughr the tail piece 4 for' the firsttime it will fill both the trapP andcasing 10.l
